When I plug in a USB GPS device, using cypress_m8 module, is creates /dev/ttyUSB0 with read/write permissions for owner,root, and group, dialout. My question is really just where are the rules for setting these permissions and how exactly are the owner and group names set when /dev/ttyUSB0 is created, i.e. a serial USB device is plugged in.
View 3 RepliesI know pretty nothing about networking'n'stuff. I got this linksys wireless router that was somewhere in a box for a few years ... now I want to see whether I can bring it back to life. I know, that I put some different software on it and that it doesn't have it's original ip assigned any more. But I can't remember which ip that would be.
So for starters I just wanted to put the original software back on to see if that thing still works. But how to do that? First I got no clue how to determine the address it is listening to. Once that'd be figured out I guess I'd have to ssh to it and install this ____.bin file I downloaded somehow.
I know in windows xp there is a registry key and an entry in the Plug and Play log file as well as maybe an event id, that is produced when a device (say usb) is plugged in. My question is, besides /var/log/ (messages?) Is there any other location that that information is stored in?
View 3 Replies View RelatedI want the following behavior in kubuntu 9.04 when I plug a device (USB stick or CD disk):
1. It should be mounted automatically for me. Now it isn't, though it appears in fdisk -l output: Code: Disk /dev/sdd: 8006 MB, 8006926336 bytes
16 heads, 32 sectors/track, 30544 cylinders

Device Boot Start End Blocks Id System
/dev/sdd1 * 16 30544 7815232 b W95 FAT32 and if I mount it manually, all goes OK
2. If I mount manually my CD disk and then press the eject button on my drive nothing happens until I manually unmount the drive. But I want it to open immediately
All this worked for me in kubuntu 8.10, and broke with the upgrade.
My fstab entries Code: /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/sdc1 /media/usb vfat noexec,codepage=866,utf8,nosuid,nodev,quiet,uid=1000,gid=1000,umask=077,user 0 0
Ubuntu 9.10. I have a problem - when I mount other partitions of my hdd or the system automounts usb disks these are mounted in /media directory with permissions 0700. So there are two problems there:
- When I switch user on my desktop to another that user can't read data from the usb disks
- I can't share data through network because smbd doesnot have read permissions on the created mount points
I think editing /etc/fstab is wrong way, there would be more right way to change permissions on mount point. I tried to change/add parameters umask, allow_other in gconf-editor (/system/storage/default_options, subsections vfat and ntfs-3g) but that does not show any results. Article [URL] recommends Open Places → Computer. Every volume except the generic File system one should have a Drive and Volume tab in its properties dialog where you can set mount options. But I did not find those tabs. Where should I set option to mount usb disks with permissions rwx for every user of my system?
I have a few websites that travel along with me in my usb stick, and I want to have read and write permisions to files on my usb by other users (i.e.: www-data) actually they have 0700. I'm running maverick (linux mint Julia).
View 1 Replies View RelatedI have a minor issue with permissions. There are a couple of devices that I need r/w access to in /dev. Whenever I first boot up and log in as end user (not root) and I need to access the devices permission is denied. Logging in as root there's no problem accessing these devices. However as an end user every time I need the devices I have to first su to root to change R/W permissions (chmod 666).
Now, the good thing is that the permissions stick even as I logout and then log back in, but as soon as I reboot my computer (every night) I have to go and chmod manually. I'm trying to find a way to avoid having to su and chmod manually but I'm not having much luck. The devices I am trying to access are /dev/ttyS1 and /dev/windrvr6, when I first boot up and login as end user the permissions look as follows:
crw-rw---- 1 root uucp 4, 65 May 27 04:11 /dev/ttyS1
crw-r--r-- 1 root root 253, 0 May 27 09:12 /dev/windrvr6
Slackware 13.0, dell vostro 1320. When I start up the laptop without the ac charger plugged in the keyboard doesn't work. This is the case when booting into runlevel 3 and 4. Then after restarting 3 or 4 times and getting sick of it, i plug the charger in, restart, get to the login screen and confirm that the keyboard works, unplug the charger and it's all good. I ssh into the laptop when the keyboard is not working and restart hald but it doesn't help. Btw, tried ubuntu and the problem wasn't there.

I recently got an old computer to use as a server and I have a whole list of things I want to do on it, but I'm having difficulties.When I installed the server, I installed AMP, FTP, Samba, CUPS, and some other items. I made a user account called 'nessdan' which (currently!) is in these groups:
www-data adm dialout cdrom plugdev lpadmin sambashare admin
The www-data group was added because I wanted to FTP my site files into '/var/www/' . Okay, that ended up working out for me. This is where things got sticky. I installed PHPMyAdmin and the files went to '/usr/share/phpmyadmin/' . I wanted to install a new theme so I downloaded it onto my Laptop, then logged in via FTP but couldn't transfer files into there! It turns out the folder was owned by 'root' and was in the group 'root'. The only thing I could come up with was to change that folders permissions so the owner was 'nessdan' and the group 'admin'. I was going to do that to the entire /usr/share/ folder but I didn't know whether or not I should be changing the permissions in the first place.
But the the trend continues! I have my print server setup and working but I wanted the server to hold the Windows drivers, so I went to '/var/lib/samba/' to do some work but noticed that a lot of the files' permissions were locked down to read only and the owner and group were 'root' . I ended up doing a 'chmod 775' and changing the owner and group to 'nessdan' and 'admin', respectively. Well I transfered over the files but now the service nmbd isn't working. The good news is, I expected to mess something up along the way and had already planned on reinstalling Ubuntu Server 10.10. I've only had the server for 4 days now and I knew from the beginning I'd be wiping it clean. I want to know how to set this thing up proper and the biggest problem is getting access into folders so I can FTP into them.When I do wipe my PC clean and start anew, how should I go about the changes that I did before (PHPMyAdmin, Samba Driver Folder)?
I wanted to assign ownership of my choice to my zip file while unzipping so I am using the command:

I have just formatted a partition that had contained a windows OS, it is now formatted to ext4 and is dev/sda1 dev/sda2 contains my Ubuntu OS and all files although the empty partition shows up in Nautilus I cannot write to it as it is owned by root.I have done some research on changing the permissions on this, but am none the wiser!!
Enabling the root account is rarely necessary. Almost everything you need to do as administrator of an Ubuntu system can be done via sudo or gksudo. If you really need a persistent root login, the best alternative is to simulate a root login shell using the following command.I cannot find gksudo and do not know what commands to use in the terminal to achieve my goal. I am in totally unfamiliar territory here, and need some fairly simple explanation and guidance to be able to claim my empty partition so I can read from and write to it.
i am trying to finish up a lab in that i have i have some accounts created under groups called "mgmt" and "pl".

We are a school and we share a samba folder with students and teacher groups. What we are trying to do is:
- Give students group users the permissions to rwx own files in folder
- Students must not be able to do anything with others files. I mean nothing so, at most, they could see the files in folder but not read it.
- Teachers can do anything with files in folder
As you can imagine, the idea is that students deliver their exams in that folder without the ability to read/copy the other students files. With sticky bit we can restrict students permissions to their own files, that is ok, but how to restrict all the permissions on other students files without restricting student access to that folder?
I am running VirtualBox on CentOS 5.4 & am not able to connect the usb ports to the guest operating systems. When I click on the device menu & usb, the devices I have plugged in show up, but are greyed out. I had this problem on Mandriva when I first started using VirtualBox & had to put my user account in the USB group. My account is in the vboxusers group but there is no USB group on CentOS & I can't figure out how to give myself permission to the USB ports.
View 6 Replies View RelatedI'm running OpenSuse 10.3 and I've tried to set permissions on my folder and subfolders from root:root to wwwrun:www. In the shell it shows all folders and files with the correct permissions, but in the GUI it still says root:root and so my web application can't write to it, until I manually set the subfolders permission in the GUI.
View 9 Replies View RelatedI've recently installed an OpenSuse 11.2 in what I'd like to be a definitive jump from windows environment.I'm not very confident yet with my linux skills, so at this moment I've yet have both systems installed with a data NTFS partition to store music, movies, documents, and general data that I'd like to use in any of the two systems. The NTFS partition has no writting permissions for anybody except root user, so I can't work anything from my personal user without starting an app like su or login as root. I want to change this by making a group (windowsWriters) where my usual user is included wich I pretend to make the group owner of NTFS partition.
I've created the group and inserted my user into it, but I'm unable to change the owner group nor any permission on NTFS partition or any of it's subdirectories. I've tried to made it through opening dolphin as su (Alt+F2 kdesu dolphin) and through chmod in consolemode logged as root, in both cases the action seems to work correctly and no error is spotted, however when I look again at the partition/folder/file permissions/ownership no changes have been made.
trying to set permissions on all subfolders by right clicking the top folder, permissions, setting the desired values, and then clicking the "Apply permissions to the enclosed files. It takes on the top Folder but not on any of the subfolders or their files.How can I set the permissions for all files and subfolders under a top level folder?

I have a file server running a cronjob to reset file permissions on a regular basis. I was thinking, I wonder if there is a way to do the chmod and chown command in a single command, as I always have to do both on the same folder, the way that you can do "chown root:users Uploads" instead of having to do two separate commands for chown and chgrp.
Then I got to thinking, are these commands even necessary? Every file copied or moved into these folders by any user needs to be something like "chmod 750" and "chgrp root:users", so rather than running a cronjob to do these modifications at regular intervals, there ought to be a way to set the folder permissions so that any files contained within will have these permissions.
The problem arises because users create documents, then a supervisor with elevated privileges can move those documents into a shared folder, however the permissions are wrong, they are user1:user1 for the owner and group and the other users can't read the file until a cronjob changes the group to be users. This has actually been acceptable, but certainly there is a better way to do this.
2 computers, Ubuntu 10.04 and Ubuntu 8.04. I have 2 folders named In and Out. Out I have set up on 10.04 for guest use. I am able to transfer files to 8.04 from that folder. Trying to set up In for a specific user to modify files. This requires a login. Both computers have the same user name and both have the same password. I set the file permissions automatically from 10.04 when electing to share In for allowed modiying. When trying to access In using 8.04, a password request window is generated with the user name already showing, and the domain name filled in as "Workgroup". The user name that shows is my login name, by the way.
View 2 Replies View RelatedI'm attempting to set up a Samba share on my lab's small server (Ubuntu Server Edition, 10.04). It looked easy enough, but the share that I set up didn't allow anyone to actually put anything on it: no uploading stuff, etc. (You can still upload files via the command line, so I implemented the unix extensions = no fix). The share is writeable and visible, and anyone can access it (according to the Samba GUI). According to the smb.conf:
[Share]
path = /home/something/Share
writeable = yes
;browseable = yes
guest ok = yes
The other Windows machines in the lab see the new server and its share automatically, although they can't make changes to it, like create a new folder in the share. Most of my lab uses Snow Leopard (OS X 10.6), and a few others use Windows. I can connect to the server using my MacBook either through the terminal or Finder -> Go -> Connect to server -> smb://blah.someplace.edu without problems.
I can do pretty much anything via the command line, but not through the Finder! If I want to create a new folder, it gives me an old-school error message (stupid blue face): "The operation can't be competed because you don't have the necessary permission." If I want to drag-and-drop a file from my desktop to the Share folder, I get a pop-up window (lock + blue face): "Type your password to allow Finder to make changes." If I do, then I get another pop-up: "One or more items can't be copied to "Share" because you don't have permission to read them. Do you want to copy the items you are allowed to read?"
I have a directory '/usr/local/games/quake4'. I want permissions for the directory, along with everything in it set to:

I am trying to figure out what needs to be done to automatically set read/write permissions for everyone for my proprietary USB device on system boot. I have created a udev rules file which changes the permissions for the device when it is connected, but it does not change the permissions when the system is booted with the device already connected. The file looks like this:
SUBSYSTEM=="usb_device", SYSFS{idVendor}=="our vendor id", MODE="0666"
Does something else need to be added to the rules file to make it work when the system boots with the device connected? Is there some other script which needs to be created somewhere?
i wonder, why nobody has written about it ...
How can i grant permission for files to specific user or specific group ??
Updated:
We have 3 groups: "g12" ("u1" and "u2), "g34" and "g56".
"g12" should only read the file.
"g34" should write and read it.
"g56" should have all permissions (rwx).
And others should not access the file at all.
one thing i can't seem to be able to do is give the guest account just these permissions: using firefox (or other browser) and using one file directory and using a text editor. means the guest can browse the net and sefe some infos form that - nothing more. the previous version had something like that, it was really easy for me, a noob, to do it with two or three clicks. if this possibiility exists, what to do. if it's not implemented... maybe it should be. 'cause many people let others use the computer but don't want any complications...

First let me say that Lubuntu is a lightweight version of Ubuntu, so there is not much point in loading it up with unnecessary packages. If you just want to share printers on a Linux network, you don't need Samba. And if you just want a way that users can "push" files to others on a network, use Giver (+ Avahi) as this is a better option. Especially as it sorts out file permissions for you.
To enable file sharing on a Lubuntu 10.10 machine, go to Preferences > Synaptic Package Manager and add the following:-
* samba
* system-config-samba
* gvfs-bin
* gvfs-backends
...accepting any dependancies, 11 packages in total.
I suggest you re-boot now. As an initial test, go to file manager (pcmanfm) and enter:-
smb://localhost
You should see the local print$ folder listed.
To access folder shares remotely
* open file manager (pcmanfm)
* enter the IP address or computer name of the machine you wish to access
e.g. smb://192.168.0.99 or smb://print-server
To share a folder:-
Go to: Preferences > Samba (enter password when requested)
In the Samba Configuration screen:-
* File > Add Share
* use Browse... to select folder to be shared
* Tick "Visible" and (if required} "Writable"
* In the "Access" select "Allow access to everyone"
Set the Linux permissions:-
* locate the folder to share in file manager
* right click on the folder and select Properties > Permissions
* set the required permissions, e.g. Other: Read & Write (to allow anyone full access)
